Neon Vision Editor v1.7.3

[v1.7.3] - 2026-09-11

Why Upgrade

• Completes macOS 27 release readiness while keeping existing deployment targets and runtime availability checks for older systems.
• Makes macOS theme changes, settings updates, and document-tab activation more responsive by avoiding redundant preference and window-composition work.
• Restores a coherent system-glass appearance across visionOS themes and reading surfaces.

Highlights

• Enables the macOS 27 Agent Mode sources in Xcode 27 App Store and notarized builds while preserving runtime availability checks and older-OS compatibility.
• Validates the application with the macOS, iOS/iPadOS, and visionOS 27 SDKs accepted by App Store Connect.

Fixes

• Prevents a theme selection from publishing ten process-wide preference changes and removes unrelated full-window composition work from theme updates.
• Avoids unnecessary editor highlighting and window-chrome refreshes during macOS settings changes and tab activation.
• Keeps visionOS System Glass light in light mode and prevents mixed light and dark surfaces in Paper and other appearance themes.

Breaking changes

• None.

Migration

• None.

Maintenance

• Moves hosted platform, release-validation, and notarized-release jobs to GitHub's xcode-27 runner and verifies the macOS, iOS/iPadOS, and visionOS 27 SDK paths before compiling them in CI; production archives continue to reject beta Xcode builds.
• Centralizes Xcode and SDK validation across CI and release workflows and correctly rejects both Xcode-beta.app and underscored beta installation names from production archives.
